摘　　要：针对参数存在的随机分布特性,应用概率论和数理统计的方法对弹簧进行可靠性分析,并建立了闭锁装置弹簧基于可靠性的优化设计模型。基于Visual Basic语言编程,用模拟退火算法优化得到弹簧参数。运用有限元法分析闭锁装置工作过程,仿真结果验证了优化结果的合理性。According to the stochastic distribution of parameters, the reliability analysis of spring locking mechanism is carried out for helical spring by using probability theory and mathematical statistics. The optimization model of the locking mechanism spring parameters is established. Using Simulated Annealing Algorithm （ SAA）, the optimal parameters of spring are provided with the help of computer program compiled with Visual Basic language. The rationality of optimization result is verified by simulation results of the finite element model.
